Answer / subash konar

Density with respect to water.If it decreases efficiency of
battery becomes low thereby decreasing current and voltage.

Answer / harish kuqhsal

SPECIFIC GRAVITY OF A BATTERY IS THE ENERGY DERIVED PER UNIT
WEIGHT OF THE CELL. WITH THIS THE VOLTAGE AND CURRENT IS NOT
AFFECTED.

Answer / manoranjan

Specific gravity is the ratio of the weight of a solution to
the weight of an equal volume of water at a specified
temperature. Specific gravity is used as an indicator of the
state of charge of a cell or battery. However, specific
gravity measurements cannot determine a battery's capacity.
During discharge, the specific gravity decreases linearly
with the ampere-hours discharged.
so specific gravity depends on volage/current.

Answer / vinod

its change with the cherge or discharge the battery.

Answer / vishal ingle

It is an indication about the charge storing capacity of a
battery. If sp. gr. decreases / increases, it affects the
voltage across terminals merely but the back up provided
will be affected adversely. In simple words, the battery
performs optimally near to the standard sp gr of 1200.

A powerplant has 8 gensets operating in grid parallel mode. In one genset sometimes there is pf variation and kvar variation. The plant operates in pf mode. When this variation is observed the load is stable, voltage is also stable, freq and genset speed is also stable. How will you check the functioning of pf card. What shall be the ideal output vdc of the pfc, from there it is input to AVR?
